Robin is a big girl - a piggy- but that's far better than living in a universe of liars like the grown-ups around her (who are almost all cheating on each other and even leching after her). The one bright spot is a multi-racial friend Tri who may or may not be a boyfriend, but seems to genuinely like her either way.
The novel has some complexity and artistry (and even some clever layout and design), but it is not a terribly interesting experience. None of the characters really grow (I'm big on character transformation!) and you end the voyage wondering why you started. A book that neither changes the reader nor the characters. What's the point?
